Vim li cas PCB ncoo dhauyoj solderingtshuabmuaj qhov tsis xws luag?
Q1:Tsim PCB tsis tsim nyog, nqaim ncoo ncoo.
A: Tsim raws li PCB tsim tshwj xeeb.
Q2:Cov pins ntawm cov khoom siv sib txuas tsis xwm yeem lossis cov plug-in yog skewed, thiab cov pins nyob ze lossis kov ua ntej vuam.
A: Cov pins ntawm cov khoom sib txuas yuav tsum tsim raws li qhov sib nrug thiab qhov sib dhos xav tau ntawm PCB.
Q3:PCB qhov kub ua kom sov qis dhau, cov khoom siv thiab PCB nqus cua sov thaum siv vuam, uas txo qhov ntsuas kub tiag tiag.
A: Teem lub ntsuas cua sov ua ntej raws li PCB qhov loj me, txheej txheej, tus naj npawb ntawm cov khoom siv, seb puas muaj cov khoom sib txuas, thiab lwm yam, thiab qhov kub ntawm sab hauv qab ntawm PCB yog nruab nrab ntawm 90 ℃ txog 130 ℃.
Q4: Vuam kub tsawg dhau los lossis siv txoj siv nrawm nrawm dhau, yog li cov viscosity ntawm cov kua nplaum yaj tau txo.
A: Tin nthwv dej kub yog (250 ± 5) ℃, lub sijhawm siv vuam yog 3 ~ 5s. Thaum qhov kub qis dua me ntsis, qhov nrawm ntawm txoj siv thauj khoom yuav tsum tau qeeb.
Q5: Kev ua dej ntws tsis zoo.
A: Hloov qhov flux
1.Lub rooj tsav tsheb yog qias neeg. Qhov no feem ntau yog los ntawm cov ntsiab lus flux tau siab, txheej ntau dhau, qhov kub ua kom sov siab dhau lossis qis dhau, lossis vim tias kev sib kis ntawm cov khoom siv claw qias neeg dhau, ntau dhau oxide thiab tin slag hauv lub lauj kaub lauj kaub thiab lwm yam.
2.PCB deformation. Feem ntau, nws tshwm sim ntawm PCB loj-loj, uas tsis muaj qhov tsis sib xws vim qhov ua tau zoo ntawm PCB loj-loj lossis txheej txheej tsis sib xws ntawm cov khoom. Qhov no xav kom PCB tsim los ua cov khoom sib faib sib npaug raws li ua tau, thiab tsim cov txheej txheem ntug hauv nruab nrab ntawm PCB loj loj.
3.Film poob (zaj duab xis poob). Thaj nplaum nplaum tsis zoo, lossis thaj nplaum ua kom sov kub tsis raug, kho qhov kub siab dhau lossis qis dhau yuav txo qhov sib zog ua kom muaj zog,yoj solderingtsis tuaj yeem tiv taus qhov kub thiab qhov cuam tshuam nthwv dej, kom cov khoom sib txuas poob rau hauv cov khoom siv lauj kaub.
4.Lwm yam tsis xws luag. Cov phom sib koom ua ke loj me, sib koom ua ke sab hauv kev nyuaj siab, sib koom ua ke sab hauv tawg, sib koom ua ke nkig, sib koom ua ke lub zog, thiab lwm yam, xav tau X-ray, ntsuas kev sib koom ua ke qaug zog thiab lwm yam kev kuaj pom. Cov kev tsis xws no feem ntau cuam tshuam nrog cov khoom siv vuam, kev ua kom zoo ntawm PCB los xij, qhov muag tau ntawm cov khoom tiv thaiv los yog tus pin thiab qhov kub nkhaus.
ZhejiangNeoDenTechnology Co., LTD., Tsim nyob rau xyoo 2010, yog cov chaw tsim khoom tshwj xeeb hauv SMTpick thiab tso lub tshuab, tso lub qhov cub rov qab, tshuab luam ntawv stencil, SMT cov kab ntau lawm thiab lwm yam khoom SMT. Peb muaj peb tus kheej R& D pab pawg thiab tus kheej lub Hoobkas, ua kom zoo dua peb tus kheej muaj kev paub dhau los R& D, kawm tau zoo tsim khoom, yeej lub koob npe zoo los ntawm cov neeg siv khoom thoob ntiaj teb.
3 qhov sib txawv R& D pab pawg nrog rau tag nrho 25+ tus kws tshaj lij R& D cov kws tsim txuj ci, kom ntseeg tau tias kev txhim kho zoo dua thiab zoo dua qub thiab kev hloov pauv tshiab;
Muaj txuj ci thiab txawj tshaj lij txhawb nqa Askiv& cov kws ua haujlwm pabcuam, kom ntseeg tau cov lus teb tam sim hauv 8 teev, kev daws teeb meem muab rau hauv 24 teev;
